Ortur laser master 1

I am trying to set up my Ortur Laser Master 1. I am completely new to this and have added it to my workshop to engrave names, messages, small pictures, etc., on my woodworking projects. I hoped this was going to be a simple plug and play process, apparently not.
I have been getting the following message when I turn on my laser;

Waiting for connection…

After looking again I noticed the, MSG:No Power Supply.
I am hoping this doesn’t mean my power source for the laser is bad. I have checked all the connections and they appear to be properly connected.
Any assistance is appreciated,
Thank you

I might suggest this indicates you will be best served reaching out to the nice folks at Ortur Support for additional assistance and diagnostic procedures. :slight_smile:

You turn on the laser engraver by holding down the furthest from the USB connector for a few seconds until the LED goes solid.
